We evaluate the impact of Success for All literacy instruction in grades 3 through 5 using data from the same cluster randomized trial used to evaluate effects in the earlier grades (K-2). In contrast to the early benefits, there is no effect on reading achievement in the later grades, either overall or for students and schools with high or low…

We use data from a randomized controlled trial of a middle school science intervention to explore the causal mechanisms by which the intervention produced previously documented gains in student achievement. Our study finds that implementation fidelity, operationalized as a measure of the frequency of implementation of the cognitive science…

This study is a randomized controlled trial that assessed the impact of Early College High Schools on students' high school graduation, college enrollment, and college degree attainment, as well as students' high school experiences using extant data and survey data. The study included 10 Early Colleges that enrolled students in Grades 9 to 12 in…

Prior research suggests that summer learning loss among low-income children contributes to income-based gaps in achievement and educational attainment. We present results from a randomized experiment of a summer mathematics program conducted in a large, high-poverty urban public school district. Children in the third to ninth grade (N = 263) were…

This article examines the effectiveness of a technology-based algebra curriculum in a wide variety of middle schools and high schools in seven states. Participating schools were matched into similar pairs and randomly assigned to either continue with the current algebra curriculum for 2 years or to adopt Cognitive Tutor Algebra I (CTAI), which…

As policymakers contemplate expanding preschool opportunities for low-income children, one possibility is to fund 2, rather than 1 year of Head Start for children at ages 3 and 4. Another option is to offer 1 year of Head Start followed by 1 year of pre-K. We ask which of these options is more effective. We use data from the Oklahoma pre-K study…

This article presents the findings of an evaluation of the eMINTS (enhancing Missouri's Instructional Networked Teaching Strategies) professional development program. eMINTS is an intensive teacher professional development program designed to promote inquiry-based learning, support high-quality lesson design, build community among students and…

This article investigates the differences in academic achievement trajectories from elementary through middle school among English Learner (EL) students in four different instructional programs: English Immersion (EI), Transitional Bilingual (TB), Developmental Bilingual (DB), and Dual Immersion (DI). Comparing students with the same parental…

Beginning in 2007, the Literacy Program at the Right Age (Pacto pela Alfabetização na Idade Certa [PAIC]) in Brazil's Ceará state required municipal schools to implement a tiered, whole-school early-grade literacy intervention. This intervention was complemented by other policies to help municipalities improve student achievement. The present…

The wage premium for college graduates is substantial. Far fewer of these benefits accrue to students who complete some college (i.e., those who do not persist to graduation), and, partly for this reason, colleges often adopt programs aimed at helping to keep at-risk students in school. This article reports on a systematic review and meta-analysis…

In this article the authors analyze the effect of private voucher education on student academic performance using new data on Chilean students and a novel identification strategy. Most schools in Chile provide either primary or secondary education. The authors analyze the effect of private voucher education on students who are forced to enroll at…

Since 1964, the Federal Work-Study (FWS) program has provided funds to subsidize the wages of student employees, but it has never been studied directly. I use an instrumental variables difference-in-difference framework with administrative data from West Virginia to identify causal effects, comparing eligible and ineligible students across…

The debates over the 2003 reauthorization of Head Start highlighted a controversy about the devolution of federal early education policy. At the center of the debate is the concern that state control of early education programs will reduce the quality and effectiveness of federal support for children living in poverty, and their families. The…

The desegregation effectiveness of voluntary plans with magnet schools was compared to that of mandatory reassignment plans with magnet schools using a sample of 20 school districts. Results show that a voluntary magnet plan will provide more long-term interracial exposure than a mandatory plan with magnet components. (SLD)

ifferent evaluation models were applied to data from a high school career education program to investigate problems in statistical conclusion validity and program effectiveness judgments. If potential threats to internal validity are analyzed and protection strategies are developed, more confidence in unplanned ex post facto design using a…
